TITLE

ZyXEL EMG2926 Command injection vulnerability in home router firmware

Trust: 0.8

sources: JVNDB: JVNDB-2017-002996

DESCRIPTION

A command injection vulnerability was discovered on the Zyxel EMG2926 home router with firmware V1.00(AAQT.4)b8. The vulnerability is located in the diagnostic tools, specifically the nslookup function. A malicious user may exploit numerous vectors to execute arbitrary commands on the router, such as the ping_ip parameter to the expert/maintenance/diagnostic/nslookup URI. ZyXELEMG2926 is a router manufactured by ZyXEL. Because the nslookup function is not fully filtered, an unauthenticated attacker is allowed to execute arbitrary code remotely
